Abstract
The Clymene dolphin (Stenella clymene) is an oceanic and elusive delphinid inhabiting the deeper waters of the tropical, subtropical, and temperate Atlantic Ocean. Despite their broad range, Clymene dolphins are relatively rare and as a result, little is known about their ecology, behavior, and population structure. In this study, we aimed to investigate the genetic population structure of S. clymene in the western Atlantic Ocean, including the WCR. DNA was extracted from 61 individuals collected in the northwestern Atlantic Ocean, the WCR, and Colombia. 500 base pairs (bp) of the mtDNA control region were amplified, sequenced, and compared with previously published data from Genbank. Population structure was evaluated using Fst and st values and results suggest significant population differentiation between the northwestern Atlantic (samples collected along the east coast of the U.S.) and the Wider Caribbean Region and Brazil
